Why and How do We Breathe?
- Understand why humans breathe, and why they developed body parts that support breathing.
- Use the model made in this lesson to explain how humans breathe, and list the external and internal body parts of a human body used for breathing.
- Explain how lung breathing is advantageous for humans or other large animals, and understand at least one other mechanism for breathing used by animals.
Breathing occurs effortlessly, but did you ever wonder how we breathe? In this lesson, students will make a model to discover how air effortlessly flows in and out of our lungs. Next, students will compare lung breathing to other ways of breathing to discover reasons why humans might have developed lungs.
Remote learning: This lesson plan can be conducted remotely. Students can work individually and independently during the Explore section guided by the video and the Student Worksheet. A set of materials can be prepared in advance. The reflect section with a discussion can be done over a video call. The Engage section can be dropped entirely
